This paper aims to make a methodological contribution for the construction of an indicator of vulnerability to landslide phenomena using variables from the study of territory with this type of threat located in Cerro Sur of Suba in Bogotá. What is intended is to begin recognizing social and economic types of variables and not only the physical ones, which can be spatialized in the territory and could, contribute to understand the vulnerable conditions. The thought of the radical geographic theory in the historical-geographical era of modernism and postmodernism is the conceptual basis for identifying spatial expressions that become generators of vulnerability, made visible on the proposed global vulnerability index.
